Abstract

Embodiments of systems, methods, and computer-readable media for providing redundant data storage are disclosed. For example, one embodiment of the present invention is a method including the steps of receiving a first signal comprising a request to store a file; generating a plurality of data blocks comprising portions of the file; computing a plurality of parity blocks based at least in part on the plurality of data blocks; and transmitting at least some of the plurality of data blocks and at least some of the plurality of parity blocks to a channel unit, hi another embodiment, a computer-readable media comprises code for a carrying out such a method.
